    wobei die ersten und zweiten Auslässe (44', 46') beide fluidisch von dem Kolbenelement während dessen gesamten Hubes entkoppelt sind, eines der ersten und zweite Einlässe (44,46) fluidisch von dem Kolbenelement während des gesamten Hubes desselben entkoppelt sind, der andere der ersten und zweiten Einlässe (44,46) von dem Kolbenelement über einen erste Teil des Hubes desselben fluidisch entkoppelt ist und fluidisch mit dem Kolbenelement über einen zweiten Teil des Hubes desselben, der der Stellung, in welcher das wenigstens eine Kolbenelement sich in der zweite Endlage befindet, fluidisch gekoppelt ist, sodass die Drehgeschwindigkeit des bewegbaren Elements (10) hydraulisch gedämpft ist.
  2. Scharnier nach Anspruch 1, bei welchem das Schließelement oberhalb eines Bodens angeordnet ist und das Scharnier an dem Schließelement oberhalb der Bodenebene befestigbar ist.
  3. Scharnier nach einem oder mehreren der vorstehenden Ansprüche, bei dem wenigstens einer der ersten und zweiten Kanäle (43, 45) eine helissenförmige Nute (47, 47') umfasst oder aus einer solchen besteht, die an der inneren Oberfläche (15') des wenigstens einen Teils (15) der wenigstens einen Arbeitskammer (13) ausgebildet ist.
  4. Scharnier nach einem oder mehreren der vorstehenden Ansprüche, wobei beide der ersten und zweiten Kanäle (43, 45) jeweils eine helissenförmige Nute (47, 47') umfassen oder als solche ausgebildet sind, die auf der inneren Oberfläche (15') des wenigstens einen Teils (15) der wenigstens einen Arbeitskammer (13) ausgebildet ist.
  5. Scharnier nach einem oder mehreren der vorstehenden Ansprüche, wobei eines der festen (20) oder bewegbaren (10) Elemente weiterhin einen Scharnierkörper (10) umfasst, der wenigstens eine Arbeitskammer (13) umfasst, wobei wenigstens einer der wenigstens ersten und zweite Kanäle (43, 45) umfasst von außen durch den Scharnierkörper (10) in den wenigstens einen Teil (15) der wenigstens einen Arbeitskammer (13) geführt sind.
  6. Scharnier nach dem vorstehenden Anspruch, wobei beide der ersten und zweiten Kanäle (43, 45) außerhalb des wenigstens einen Teils (15) der wenigstens einen Arbeitskammer (13) durch den Scharnierkörper (10) geführt sind.
  7. Scharnier nach einem der vorstehenden Ansprüche, bei welchem wenigstens einer der wenigstens ersten und zweite Kanäle (43, 45) oder beide der wenigstens ersten und zweiten Kanäle (43, 45) wenigstens ein Element (110) zur Steuerung des Durchflusses des Arbeitsfluids umfasst, sodass die hydraulische Dämpfung der Drehgeschwindigkeit des bewegbaren Elements (10) einstellbar ist.
  8. Scharnier nach dem vorstehenden Anspruch und Anspruch 5 oder den Ansprüchen 6 und 7, bei welchem dass wenigstens eine Element (110) zur Einstellung des Durchflusses des Arbeitsfluids eine Stellschraube ist, die ein erste oberes Gewindeende (116') umfasst, welches in ein entsprechendes erstes oberes Verbindungsteil (11') des Scharnierkörpers (10) mit Gegengewinde eingeschraubt ist, und die ein zweites unteres Ende (116") umfasst, das verschiebbar in ein entsprechendes zweites unteres Führungsteil (11') des Scharnierkörpers (10) eingesetzt ist, wobei das zweite untere Ende (116") einen hohlen Sitz (119) umfasst, der dazu ausgebildet ist, ein im wesentlichen kegelstumpfförmiges Element (120) aufzunehmen, das konisch in diesen (119) eingesetzt ist, wobei die Einstellschraube (115) eine erste Öffnung (121) für den Einlass des Arbeitsfluids umfasst, die innere Oberfläche (122) des hohlen Sitzes (119) der äußeren Oberfläche (123) dem im wesentlichen kegelstumpfförmigen Element (120) zugewandt ist, um einen Zwischenraum dazwischen zu definieren, der fluidisch mit der erste Öffnung (121) für den Einlass des Arbeitsfluids und mit einem zweite Kreis verbunden ist, wobei der Zwischenraum dazwischen angeordnet ist.
  9. Scharnier nach einem oder mehreren der vorstehenden Ansprüche, wobei die Dämpfungsmittel (40) weiterhin gegenwirkende elastische Mittel (41) aufweisen, in der zweiten Endlage das wenigstens eine Kolbenelement einer Anschlagfläche (14) zugewandt ist und die zweiten gegenwirkenden elastischen Mittel (41) zwischen dem wenigstens einen Kolbenelement und der Anschlagfläche (14) angeordnet sind.
  10. Scharnier nach Anspruch 9, wobei die zweiten gegenwirkenden elastischen Mittel (41) ein Ende (42) umfassen, das wechselseitig dem wenigstens einen ersten Kolbenelement zugewandt ist.
  11. Scharnier nach dem vorstehenden Anspruch, wobei die zweiten gegenwirkenden elastischen Mittel (41) dazu ausgebildet sind, von einer unbelasteten Stellung, in welchem das Ende (42) derselben (41) von dem ersten Kolbenelement beabstandet ist, in eine beginnende Belastungsstellung bewegt zu werden, in welcher das Letztere in Berührung mit dem Ersteren (42) ist, um die gleichen zweiten gegenwirkenden elastischen Mittel (41) zu belasten, um mechanisch die Drehgeschwindigkeit des bewegbaren Elements (10) zu dämpfen.
  12. Scharnier nach dem vorstehenden Anspruch, bei welchem ein Schub auf das Kolbenelement die zweiten gegenwirkenden elastischen Mittel (41) von einer beginnenden Laststellung in eine End Laststellung bewegt, in welcher die zweiten gegenwirkenden elastischen Mittel (41) vollständig belastet sind.
  13. Scharnier nach einem der Ansprüche 9 bis 12, bei welchem das Kolbenelement einen zylindrischen Körper (55) und eine Welle (53) umfasst, die teleskopisch mit der Anschlagfläche (14) gekoppelt ist, wobei die gegenwirkenden elastischen Mittel (41) eine Spiralfeder umfassen, die auf die Welle (53) aufgesetzt ist.
  14. Scharnier nach dem vorstehenden Anspruch, wobei der zylindrische Körper (55) einen verlängerten Fortsatz (55") aufweist, der sich koaxial zu der Welle (53) in Richtung auf die Anschlagfläche (14) erstreckt, um einen ringförmigen Sitz (51') dazwischen zu definieren, der dazu ausgebildet ist, die Spiralfeder (41) aufzunehmen, wenn Letztere sich in der beginnenden Belastungsstellung befindet.
